CASTRATING-TOOL.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed February 11, 1907. Serial No. 356,864.

To all whom it may concern:

Be it known that I, JOHN N. GAssETT, a

citizen of the United States, residing at Laurin, in the county ofMadison and State of Montana, have invented a new and useful Improvementin a Castrating-Tool, of which the following is a specification.

This invention relates to castrating tools and more particularly tocastrating tools especially adapted for castrating lambs, the objectbeing to provide a tool with a pair of grippers and a cutting blade sothat either the grippers or the knife can be used, thereby overcomingthe difficulties of having to put down one tool and take up another.

With these objects in view, the invention consists in the novel featuresof construction, combination and arrangement of parts here inafter fullydescribed and pointed out in the claims.

In the drawings forming a part of this specification:Figure 1 is a sideelevational view of my improved castrating tool showing the bladesopened. Fig. 2 is a top plan view of my improved tool showing the bladesclosed. Fig. 3 is an end view of the tool.

In the drawing A indicates a handle pro vided with a curved jaw A havingan enlarged serrated gripping portion A A slot A is formed obliquely inthe handle in respect to the jaw, in which is pivotedlymounted a knifeblade B on a pivot pin B, the blade being held in a closed or openedposition by an ordinary spring B secured in the slot A An enlargement Ais formed on the handle A adjacent its outer end forming a stop toprevent the hand from slipping down on the blade when using the same.The handle is provided with an enlarged bifurcated portion A in which ispivotedly mounted on a pin C, the reduced enlarged portion of a shorthandle D which is provided with a curved jaw D, having an enlargedserrated gripping portion D adapted to bear against the en largedportion A of the handle A. A lug is formed on the under side of thehandle D on which is arranged a coil spring E, the

lower end of which fits over 2, lug formed on the handle A so that thegripping portion of the jaws will be normally held together.

It will be readily seen that by gripping the handle A and pressing downon the short handle D with the thumb, the jaws can be opened so as togrip the testicles so that the testicles can be readily pulled out.

From the foregoing description it will be readily seen that I haveprovided a very novel castrating tool, so constructed that it can bereadily carried in the pocket and one in which the knife or gripper canbe used as desired without putting the tool down, thereby saving a greatamount of time.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. A tool of the kind describedcomprising a handle having a slot formed in one end and a jaw formed onthe other end, a knife blade pivotedly mounted in said slot, a shorthandle mounted on said handle provided with a jaw at one end, and aspring arranged between said handle for holding said jaws together.

2. A tool of the kind described comprising a handle having a curved jawat oneend provided with an enlarged serrated gripping portion, saidhandle having an oblique slot formed therein in respect to the jaw, astop formed on the handle adjacent its end, a knife blade pivotedlymounted in said slot, an enlarged bifurcated portion formed on saidblade, a short handle provided with an enlarged reduced portionpivotedly mounted in said bifurcated portion, a jaw formed on saidhandle provided with an enlarged serrated gripping portion, and a coilspring arranged between said handles for holding the serrated enlargedgripping portion to gether.
